INDIRECT FULGURATION ELECTRODE.

The present invention relates to an im provement in electrodes adaptedto be-employed inthe therapeutic use of loiv voltage high frequencyelectrical. currents bythe fulguration process, which has nonv become acommon one in the application of electrical treatments to the humanbody.

The device of the invent-ion may be generally referred to as a fingerrhcostat, inasmuch as it contemplates the control of electrical currentby simple manipulation of the fingers of the physician, or other user,though it will be understood that, from certain aspects, the inventionmay be of broader scope than might be indicated by this designation.

In order that the use of this device may be clearly understood, itshould be known that the process of treatment contemplated is theindirect method in which the patient may be positioned on anauto-condensation pad, to which current is supplie-d from a highfrequency apparatus of any desired form. The current with which the bodyis charged may then be Withdrawn at the point of application of theelectrode.

A principal object of this invention is the provision of a controllingdevice adapted for simple manipulation to control the amount of currentWithdrawn from the body.

Other objects and advantages of the invention will be apparent as it isbetter understood from the following description, which, taken inconnection With the accompanying drawings, iscloses a preferredembodiment thereof.

Referring to the drawings,

Figure l is a perspective view of a device in which my invention isembodied, illustrating the method of control;

Fig. 2 is a plan view of the insulated control member, showing the meansWhereby it is connected to the fulguration point; and

Fig. 3 is a longitudinal section of the parts shoivn in Fig. 2.

As thus illustrated, the electrode of my invention comprises afulguration point 2l, which is held in an insulated handle 22 andconnected by a Wire 23 With 'a controlling device generally indicated bythe reference character 24. Said device comprises a current conductingplate, or bar, 25, which may lo@ Q German silver, or other suitable material, and is embedded in an insulating hand piece 26, which latter hasinserted therein7 from one end, a rod 2T contacting at one end with theivire 2? and beingv connected With the bar by means of screws 28, whichserve at once to hold said bar 25 in place and yto establish electricalconnection with the rod 27.

The Wire 23 is enclosed in a tube 29, which may be of rubber, `or othersuitable material, as also may the hand-piece 22. The handpiece 26 isprovided VWith a recess 3l at one end to receive the tube 29 and it willbe noted that the Wire 23, extending through the tube at this end,enters the body of the rod 27, as sho-Wn at 32. A. projection 33, at oneend of said hand-piece, is slotted at 34 and the other end of thehand-piece is slotted at 35 to receive an elastic band, or strap, 36, bywhich said hand-piece may be held on the hand of the user, in theposition shown in Fig. l.

lVith said hand-piece positioned as shown, the bar 25 may be engaged byone or more of the fingers of the hand of the user, which latter isindicated by the reference character 37. Thus more or less resistance isprovided to cont-rol the current drawn by the fulguration point 21, itbeing understood that said current is grounded through the body of thephysician, or other user of the device.

A suitable insulating support may be provided for the right hand Whichengages the handle 22 and the physician may concentra-te his attentionupon said point While controlling the operation by simply manipulatingthe fingers of his other hand.

It is thought that the invention and many of its attendant advantageswill be understood from the foregoing description, and it Will beapparent that various changes may be made in the form, construction andarrangement of the parts Without departingfrom the spirit and scope ofthe invention, or sacrificing all of its material advantages, the formhereinbefore described being merely a preferred embodiment thereof.

I claim:

l. An indirect fulguration electrode, comprising a fulguration pointadapted to be held adjacent the body of a patient subjected toelectricall current, and a control connected With said point, saidcontrol being adapted to be held in the hand of the user and manipulatedby contact of one or more lingers therewith to vary the amount ofcurrent drawn troni the patient.

An indirect tulguration electrode, coniprising av ulguration pointadapted to be held adjacent the body of a patient subjected toelectrical current, and a control comprising an insulated currentconducting ineniber connected 'with said point and adapted to be engagedby one or niore lingers ot' the user to vary the arnount ot' currentdrawn from the patient.

3. An indirect lulguration electrode, coinprising a tulguration pointadapted to be held adjacent the body of a patient subjected toelectrical current, and a control coinprising yan insulated currentconducting member adapted to be secured to the hand o'l the user andconnected with said tulguration point whereby the amount of currentdrawn trein the patient: may be varied in accordance with 'the extent otContact niade by one er inore et the users lingers.

An indirect :tulguration electrode, coinprising a 'fulguration point, aninsulating handle by which said point niay be held in position adjacenta part to be treated on the body of a patient subjected to electricalcurA rent, and a control connected with said point and adapted to haveinore or lees resistance put in circuit therewith by the progressiveremoval ot the eperators fingers whereby to Vary the amount of currentdrawn from the patient.

5. n indirect ulguration electrode, coinprising a fulguration point, aninsulatinr handle by which said point may be held in position adjacent apart to be treated on the body oi a patient subjected to electricalcurrent, and a control connected with said point and adapted to haveinore or less resistance applied thereto whereby to Vary the amount ot'current drawn from the patient, Said hanH dle being adapted to be heldin one hand of the user and said control being adapted to be held in theother hand and manipula ed by engagement of one or more lingerstherewith.
